Acrylic luminous letter production method and steps

01

Draw the desired words on the MDF with copy paper, leave 5 cm on each of the four sides, install the corresponding straight knife with a manual engraving machine, and open the mold along the outer line of the word (the inner line, the other line). After the mold is opened, use a file to flatten the mold. Then use a file and sandpaper to grind the sides and corners of the yin and yang mold of the word into a circular arc, be sure to be smooth and uniform, and finally use sandpaper to smooth it. You can also use the computer engraving machine to engrave the mold, add enough height after the high edge and angle processing smooth.

02

The production requirements of the bottom plate, the four sides of the male mold of the bottom plate should be treated smoothly, and the four corners should be ground into a circular arc and inclination (that is, the four corners are narrow and wide) to facilitate mold release. The bottom of the bottom plate can be ground with sandpaper, and the angle is not too large, so that the gap between the two bottom plates can be narrowed. Acrylic light box bottom plate mold calculation method Acrylic light box bottom plate mold calculation method has two cases, these two algorithms are for equal parts cut into several pieces of the bottom plate.

03

The algorithm for dividing the mold horizontally or vertically into several pieces is as follows: subtracting the dimensions of the edges on both sides of the bottom plate with the total length is equal to the total length of the remaining mold to be made. The total length of the remaining mold to be made divided by the number of equal parts of the divided blocks is equal to the size of the mold to be made of the bottom plate With the total width minus the left edge size on both sides of the bottom plate is equal to the inch of the bottom plate mold to be made, the size calculated by 2 is reduced by 5 mm, which is the loss of the gap between the two bottom plates when splicing (that is, the loss of loose splicing) The length of the final total size, after the molding of multiple acrylic bottom plates are spliced together, look for them on both sides of the bottom plate.

04

First of all, there must be a literal carving, around the literal on the iron to draw the bottom shell cut out, and then surround the word edge strip, weld the word bottom shell, in the bottom shell row led module!! Connect the line! Put the enclosed literal buckle on the bottom shell and tighten the screws with drill holes on the side straps.



05

The positive wiring of each string of lights is welded in parallel with a long red wire, and the negative wiring is welded in parallel with a long black wire. Connect the red wire to the positive pole of the 5v or 12V power supply for the LED, and the black wire to the negative pole of the 5v or 12V power supply for the LED (the positive and negative poles cannot be reversed) The sealing glue fixes the LED to the tin sheet. Test aging: After connecting, turn on the power. Check the treatment for non-bright ones, and then perform an aging test for 24 to 48 hours.

Precautions

Acrylic bottom plate with acrylic word cooling problem. According to the physical properties of acrylic sheets, the optimal cooling time is 24 hours, and it takes at least 12 hours to use. Acrylic bottom plate cooling method: After the acrylic bottom plate is taken out of the platform, it is reversed to the four sides of the bottom and cushioned with a bracket, so that the bottom plate is suspended and does not let the acrylic bottom plate face the ground. The upper middle parts of the four sides of the acrylic base plate are compacted with heavy objects, and then the blowgun is blown while pressing its surface with the hand to quickly cool the surface of the inverted surface. Press for a period of time before use. Cooling method of acrylic words: After the acrylic word is taken out of the platform, it is placed in a flat place and pressed on the four sides with a heavy object to prevent the bottom from deforming.

The thickness of the acrylic plate is applicable to how large the acrylic light box bottom plate 1, 3 thick plates are only suitable for the acrylic light box bottom plate of about 1 meter. If the area is too large above 1.5 meters, it is necessary to take into account the physical characteristics of the plate itself, such as bearing capacity, elasticity and tensile force, and 4-5 thick plates can be selected according to the local weather conditions, the size of the wind and other conditions.
